          We proposed the reconstruction method of sparse radial
          
           k-t
          
          SPIRiT, 
						which combines sparsity constraint into radial
          
           k-t
          
          SPIRiT 
						for highly accelerated dynamic imaging with high 
						spatiotemporal resolution. The efficiency of the 
						proposed method was demonstrated by phantom and
          
           in-vivo
          
          liver 
						data acquired with golden angle radial trajectory. The 
						proposed method has higher SNR and less striking 
						artifacts compared to SPIRiT and radial
          
           k-t
          
          SPIRiT 
						reconstruction without sparsity constraint.
